This was posted on Optics Talk by koshkin. It is a given over there, that beginning 3 years ago, the Pentax scopes were made by Burris. There is no better source on the web for scopes. Koshkin writes:
"There have been a few discussion here and there regarding the difference between Pentax and Burris scopes. I've been scouring the net for information on that and on the new Gameseeker scope line. Not sure if anyone except me still cares about this, but here we go. Presumably, this comes from a PentaxUSA division manager:
Pentax and Burris scopes (except for Gameseeker) are the same.
Burris makes mechanicals here in the US, and Pentax makes the glass in Japan.
Various Pentax Lightseeker scopes are the same as Burris Signature Select and various Diamonds and are made here in US.
Pentax Pioneer and Whitetails Unlimited are the same as Burris Fullfield II. Burris Fullfield II and Pentax Pioneer are, for the most part, assembled in Phillipines out of the same components as the scopes assembled in US. Some Burris Fullfield II scopes and all Pentax Whitetails Unlimited scopes are assembled in the US out of the same components as the Phillipine assembled scopes. Hence the price difference between otherwise identical Pentax Pioneer and Pentax Whitetails Unlimited.
When moving production to the Philipines, Burris took their Colorado factory and moved the machinery to the Philipines and trained local workers, so this is not the case of subcontracting. This is a Burris-owned factory.
As for the Gameseeker scopes, from what I've been able to find out, they are made in China. I am not sure who makes these for Pentax though (or if it is a Pentax facility in China). Presumably they are desinged to be just as good as Nikon Buckmaster at lower price point. Once they hit the market I'll buy a couple and play with them. Maybe I'll even challenge cheaptrick to a Buckmaster agains Gameseeker comparison test."
